Source files

Suppliers

Twenty suppliers the room has bought from and argued about. Each source file records what the channels have said over time, a chronological verification log linking to real message anchors, and the room's own aggregate score.

How to read these

Scores are this room's own, from member reports logged in #vendor-talk, #vendor-verification and #test-results. They are not comparable with any other community's numbers and they are not for sale. Each supplier page links to its storefront so a member can check a source directly. The room sells nothing and takes nothing from any supplier. A low score means members reported problems with fills, variance or support — it is not an allegation of fraud, and the room keeps those words separate.

Everyone else that gets named

The twenty above have source files because the room has bought from them repeatedly and argued about the results. The 188 below come up in the channels without ever accumulating enough for anyone to say much. No source file, no score, no link — that is the state of the record, not a verdict on the company.
